Fesoterodine is sold in the US under the brand name, Toviaz. The medicine is given on a doctor's prescription and comes in extended-release tablet format.
Fesoterodine is one of a class of drugs called antimuscarinics. It is used in the treatment of patients who have an overactive bladder. Overactive bladder typically causes uncontrollable contractions of the bladder's muscles, resulting in uncontrolled urination, a frequent urge to urinate and an urgent need to urinate.
The medication works by causing the muscles of the bladder to relax, thus effectively relieving the symptoms of the condition.
Fesoterodine cannot cure your overactive bladder problem, but it will do much to control it. You may have to use this drug for the rest of your life in order to maintain its effect.
